Title: Improvements in control arrangements of carrier transmission systems
IPC: H04B3/10
Filed: 1939-01-10
Abstract: 523,615. Transmission systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, F. C., HODGSON, K. G., and ROCHE, A.. H. Jan. 10, 1939, No. 807. [Class 40 (iv)] In a carrier wave transmission system wherein one or more pilot frequencies are transmitted for synchronization and transmission control purposes, the pilot or pilot frequencies are rendered effective for transmission control only during intervals when the signal level has fallen below a predetermined value. The carrier itself may be used as a pilot and pilots within the signal range may be used. The transmission control pilots may be made effective at the receiver, or they may be transmitted only during the said intervals. The pilots controlling flat gain and equalization may operate in succession. In the transmitting arrangement shown in Fig. 1, the modulator M1 is supplied with carrier frequency of 42.5 k.c. from an oscillator O1 controlled by an oscillator 02 operating at 34 k.c., the carrier and one side band being removed by filter BP1 from the output of the modulator. A small portion of the outputs of both oscillators is passed to the line through filters F1, F2 to act as pilot frequencies the connection to the line being, for example, as described in Specification 513,229. At the receiver, Fig. 3, the signals and pilots pass through an equalizer E2 and attenuator AT1 to an amplifier A2 and thence, with the pilots excluded at BP2, to the demodulator M2. The 34 k.c. pilot is received at PI2 and operates a level indicator M1 only when relay R in response to the fall of signal level below a predetermined value as detected at D. Receiver PI1 does not therefore affect the quality of transmission during signal reception. The indications of m1, m2 are used to control AT1 and E2, but in the modification shown in Fig. 4, this control is effected automatically, by any known means, and in succession. When PI2, is controlling the flat gain at AT1. relay R2 renders control of the equalizer E2 by PI1 ineffective. The gain and equalization control may be effected in a feed back path of amplifier A2. Equalization may be effected over a number of sub-bands by pilot frequencies made effective insequence.

Title: New alkyl aromatic lubricating fluid
Inventor: TOOMASU REJINARUDO FUOOBASU
IPC: C08F8/02
Filed: 1990-01-05
Abstract: Aromatic compounds are alkylated with C20-C1300 olefinic oligomers by contacting the oligomers and aromatic compounds with an acidic catalyst to produce novel alkylated aromatic hydrocarbon compositions useful as lubricant basestock and additives. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced chromium oxide catalyst on silica support. In one embodiment, the aromatic compounds are alkylated with a mono-olefinic HVI-PAO dimer which is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. The novel alkylaromatic compositions show improved thermal stability; also, the compositions are useful as lubricant additives for improved antiwear properties, antioxidant and other properties.

Title: Starting method of fluidized bed type furnace with solid fuel
Inventor: FUJIWARA NAOKI
IPC: F23C10/18
Filed: 1980-01-09
Abstract: PURPOSE:To reduce the starting cost by enabling the starting of a fluidized bed type furnace with a solid fuel easily available by arranging the solid fuel on a layer of fluidizing medium yet to be fluidized to start combustion with the ignition thereof before the fluidization of the medium. CONSTITUTION:When starting a fluidized bed type furnace, a fluidizing medium is packed on a porous plate 3 of the body 1 thereof to form a nonbreathing stationary layer 2a. Then, coal, wood or other solid fuel 10 is placed into the stationary layer and ignited with a match, an igniting burner 11 or the like. The solid fuel 10 is burned being fed with combustion air A2 from the furnace side wall. After the progress of the burning to a certain extent, a fluidized air A3 is introduced from the lower part of the layer through the porous plate 3 and turns the stationary layer 2a to a fluidizing layer by fluidizing it. Consequently, the solid fuel 10 is mixed into the fluidizing layer 2 as a kindler 10a to heat the fluidizing medium. After the temperature reaches a certain level, matter to be burnt is dumped into the furnace then, the furnace is put into operation.

Abstract: PURPOSE:To improve quantum efficiency, and to increase the speed of response sy mounting a reflecting article on the back of a pellet. CONSTITUTION:A pellet layer is thinned only by a section corresponding to an operating region 15 except a depletion layer in an N<-> type semiconductor region 12 and a substance reflecting incident beams 16 having a wavelength used in a photodiode such as a reflecting article using Au as an electrode metal is fitted under an N<+> type semiconductor region 11, and incident beams 16 are reflected. Since the operating region 15 except the depletion layer is removed, the depletion layer 14 extends over the whole of the N<-> type semiconductor region 12, and incident beams 16 are projected into the depletion layer 14 again as reflected beams 26 by a reflecting plate 21. Accordingly, the state in which the depletion layer effectively extends over the whole of the N<-> type semiconductor region 12 even by a non-bias or a low bias is brought about, and it is expected that quantum efficiency is improved and the speed of response is increased.

Abstract: PURPOSE:To prevent the deterioration of performance of a shared memory that is caused by a bus neck by locking a bus only when a shared memory use control table is updated in order to secure the shared memory and then updating a lock flag. CONSTITUTION:When a shared memory security request acceptance means 11 accepts a security request of a shared memory 20, the using state of a shared memory use control table 21 is decided based on a lock flag 22. Then a bus 5 is locked to perform the exclusive updating of the table 21 when it is decided that the table 21 can be updated, and the bus 5 where the updating of the flag 22 is locked is unlocked. In other words, it is just required to lock the bus 5 and to update the flag 22 only when the table 21 is updated so that a processor secures the memory 20. Thus it is possible to shorten the locked time of the bus 5 and to prevent the deterioration of the performance of the memory 20 due to a bus neck.
